SPECIFICATION forming part of' Letters Patent No. 694,252, dated February 25, 1902. Application filed January 2, 1901. Serial No. 41,841. (No model-l T @ZZ whom. it nur/y concern: YABe it known that I, NORMAN COLLINS, engineer, a subject of the Queen of Great Britain, residing at Monument Square Chambers, London, E. C. ,England, haveinvented certain new and useful Improvements in Cash-Registering Machines, of `which the following is. a specification.

This invention relates to improvements in,A 1o apparatus for registering cash receipts, such as described in thespecitication of previous Letters Patent dated June 20, 1399, and numbered 627,403; and the improvements have for object to furnish printed records yof each individual amount received and of the aggregate of that and of the several amounts previously recorded, as well as a record of the time at which `each transaction is registered. The improvements also-have for object to zo insurethe proper working of the apparatus under all circumstances and to prevent the falsification of the record through omission to complete the registration by 'printin g a record of a transaction in respect of whicha key mayhave been depressed.

Theimprovements alsohave for object to en-y able a separate time-record to be printed with-v out altering the cash record in order to show, for example, the times of opening and closing 3o the registering-machine for purposes of` busi-V ness and to provide for the use of a detector whereby to enable the approximate times of inspection to be recorded. An incidental ad vantage is that the entire mechanism may be of the machine outside business hours;

Reference is to be'had to the accompanying drawings, wherein Figure 1 is a general plan of the cashregistering machine, the 4o clock mechanism being omitted. Fig. 2 is a transverse section on line A A, Fig. 1. Fig'. 3 is a right-hand end elevation of :the mechanism within the casing. Fig. 4 is a left-hand end sectional elevation showing the inking and printing mechanisms. Figs 4 and 4b are detail views of the same. Fig. 5 is a detail of the cam mechanism for producing a sudden action in printing the records. Fig. 5 is a side elevation, partly in section, of the 5o same.

The same reference-numerals indicate the same parts in all the figures.

The apparatus resembles that described in the specification of the previous patent afore-A said in so far that it comprises separate banks ofkey-levers and separate spring-revolved stud-barrels, (one foreach denomination ot' the monetary system in use,) each barrel when released bythe action of a key in the corresponding vbank performing a completerevolution in two stages, the first partial-revolution occurring when a key isdepressedand corresponding in amplitude to thevalue of the key actuated and the complement of the revolutiod'being performed when the key rises. In the present apparatusthe latter portion of therotation of the barrel is'utilized to reset the type-wheels by which the detail record is printed, and ther rewinding (after each operation ofthe barrel or barrels which have beenreleased) is effected by the revolution of a han d-operated shaft from which the entire recording mechanism is operated or controlled instead of the rewinding beingperformed by the depression ofthe 'keyitself In the drawings, l 2 3 are spring-revolved stud-barrels, to which correspond banks of keys respectively for the registration of amounts in pence, shillings, and pounds, they three barrels vbeing in axial alinement and.

preferablyvmounted to rturn about the same.l

stationary7 spindle 4, the spring 5 of each barrel being attached at its inner end to a sleeve 6, turning on the spindle 4, andthe barrel turning upon the sleeve. Each of the studbarrels 1 2 3 is geared directly with a type- IOO wheel of corresponding denomination for printing such part of the record of each individual vtransaction as is expressed in that denomination,the type-wheels corresponding, respectively, to the stud-barrels 1 2 3 being denoted by the figures 7 8 9 and each barrel 1, 2, or 3 determines by its partial rotation (permitted by the depression of a key in the bank corresponding to that barrel) a corresponding partial rotation of the correspond` ing type-wheel 7, 8, or 9, so that it will be brought to position to print a value corresponding to the value represented by the key depressed. The subsequent partial rotation of the barrel permitted by the rise of the key and forming the complement of a single revolution of the barrel effects the return of the said type-wheel to Zero. For this purpose each barrel has a gear-wheel 10 fast therewith, which gears through an intermediate wheel 11 with a wheel12, fast on the shaft 13, 14, or 15 of the type-wheel 7, 8, or 9, respectively, the gear-Wheels of each set being of equal diameters, so that one revolution of the barrel produces one revolution of the corresponding type-wheel shaft. The shaft 13 of the pence type-wheel 7 passes through the shillings and pounds type-wheels 8 9 and through their shafts 14 15, which are tubular, the shaft 15 being sleeved upon shaft 14.

The key-levers of all the banks are pivoted on a cross-rod 16, and the mechanism of t-he key-levers and stud-barrels of all the banks is similar. Each comprises a motion-transmitting cross-bar 18, which is common to the keys of that bank and is lifted when by the operation of` any key in the bank the rear end 17 of that key is raised. The cross-bar 18 is carried by arms 19, pivoted on the crossrod l16, the one arm 19 of the cross-bar frame being formed with a cam 20, engaging a stud and friction-roller on a detent-lever 21, loosely pivoted on a shaft 22 and engaging by itslug 23 witha stud 24 on the barrel l, 2, or 3, Whereby the latter is normally retained at the zero position. The barrel has peripheral studs 25 for engagement by the respective key-levers and spaced at equal angular distances around the barrel, there being a stud corresponding to each key in the bank. Each key-lever 17 is provided with a detent 26 for engagement with the corresponding stud of the barrel, said detent being formed, preferably, by a pair of plates 27, pivoted on the rod 16 and straddling `the key-lever, the plates being connecte'd by cross-studs 28 29, the one above and the other below the key-lever, so that the detent 26 will be moved by the lever with freedom for a certain amount of lost motion. The detent 26 is pressed upward bya spring 30, so that it will have a less angular movement than the key-levers, and will consequently come into the path of the corresponding stud 25 before the key-lever completes its stroke in the Lone direction and will remain in engagement with the stud until the keylever has nearly completed its return stroke.

With each barrel l 2 3 there is combined a shaft 3l, 32, or 33, these shafts being sleeved concentrically one on another and serving for adjusting type-wheels 34 35 96 97, which at each operation of the machine print (concurrently with the record printed by the detail type-wheels 7 8 9) a record of the total or aggregate of previous records and of the amount which may be in course of registration. For this purpose each barrel 1 2 3 is geared with the corresponding shaft 31, 32, or 33 by means of a spring-actuated coupling which comes into action when the cross-bar 18 is raised by the operation of any key in the corresponding bank, so that at the same time that the corresponding type-wheel 7, 8, or 9 (for printing the detail cash record) is moved from Zero to an angular extent corresponding to the value of the key operated the type wheel or wheels 34 35 96 97 pertaining to the corresponding denomination for printing the total cash record will be advanced to an equal angular extent from the position which it previously occupied. The said coupling comprises a gear-Wheel 37, fast on the shaft 31, 32, or 33, the said gear-wheel being in axial alinement with the intermediate Wheel 11, which turns loose on the same shaft 3l, 32, or 33. The two wheels 37 and 1l are equal and have their .teeth in alinement and are sufficiently adjacent to one another to be both geared with the same broad pinion 38 when the latter is moved'latterally,'as hereafter described, so that at the same time that motion is transmitted from the stud barrel through the wheels 10 11 12 to the shaft 13, 14, or 15 of the detail type mechanism an equal amount of motion will be transmitted from the same barrel through the Wheels 10 l1 38 37 to the corresponding shaft 31, 32, or 33 of the totalizing type mechanism. The three pinions 38 are loose on the same rod 39, which is fitted to slide longitudinally in bearings in the frame of the machine, and the three pinions 38 are each constantly in gear with a wheel 37 and are constantly pressed in the direction of engagement each with the corresponding wheel ll by a spring 40, but are each normally held out of engagement with Wheel 11 by a stop 4l, engagingin a peripheral groove 42 in the boss of the pinion 38. The said stop 4l is carried by a link 43, jointed at 44 to one of the arms 19 of the cross-bar frame, and is guided by a fixed stud 45, engaging in a Vertical slot 46,0r otherwise, so that as soon as the motion-transmitting cross-bar 18 begins to be raised by any key* of the corresponding bank the stop 41 will be disengaged from the corresponding pinion 38, which will therefore be vforced by its sp1-ing 40 into gear with the corresponding wheel 11. The corresponding totalizing type-wheel shaft 3l, 32, or 33 will thus be coupled to the studbarrel before the latter is allowed to move from normal position bythe release of its stud 24 from the detent 23 2l through the operation The coupling-pinion 38 is disenof cam 20.

gaged from the wheel 11 by the operation of a cam 47 ,which engages with a stud 48 on an arm 49, rigidly attached to the slide-rod 39. The cam 47 is fast on shaft 22,which shaft is geared with the hand-operated main orrfirst-motion shaft 50 (upon the revolution of which the operation of the machine is dependent) through a pair of equal gear-wheels 51 52, respectively by a collar 53, lixedon the rod 39 and which is caused to bear against the bossof the pinion 38 and to move said pinion longitudinally, so as to compress its spring 40 and permit the rengagement of the stop 4l with the groove 42 when the cross-bar frame 18 19 falls. In this position the pinion 38 is caused to engage by two adjacent teeth with a fixed stud 66, whereby the gear-wheel 37 and the shaft 31, 32, or. 33 will `be locked against angular in the locked position by the s'top 41, and on the completion of its revolution the cam will displacement, so that before the cam 47 completes a revolution the pinion 38 is retained so move the rod 39' as to withdraw the collar 53 out of the wayof the pinion 38 in readinessfor the next coupling operation. The coupling and uncoupling operations aresimultaneously effected in respect of two or more of the pinions 38, whereof the correkspending stud-barrels may be simultaneously brought into' action by the simultaneous op eration of keys in different banks.

The rewinding of the spring of each studbarrel which may have been thus permitted to operate yis effected (by a revolution of the shaft 50) through the `medium of a clutch on the shaft 22, which clutch is thrown into gear through the agency of the corresponding cross-bar 18 when that cross-bar is raised, the one member of each clutch being fast with the shaft 22 and the other member being'fast with a sleeve 54, loose on Ithe shaft 22 and fast with a wheel- 55'which is coustantly in gear with an equalwheel 56, fast on the sleeve 6 of the barrel to which the clutch appertains.v The one member of the clutch. may consist of an arm 57, carrying a 'stud 58, parallel with the shaft -22 and adapted to engage in a hole 59 in a disk 60,

formingthe other member of the clutch.

The sleeve 54 is free tobe slid on the shaft 22and the sliding member is thrown into engagement with the other member of the clutch bythe action ofy a roller 61.(mounted on a bracket62, rising from the cross-bar 18) pressing against therounded edge andV back of the disk 60, and thereby overcoming-the pressure of a spring 63, by which the two members of the clutch are normally separated. This engagement of the clutch occurs when by the operation of a key the cross-bar 18 is raised, and it has for effect both to throw the clutch into gear and to disengage the movable member 60 of the clutch from an arm 64, which is fast on the frame of the machine and normally engages in a notch in the disk 60 and which when so engaged forms the abutment for the barrel-spring 5.

The wheels 11 and 37 to be coupled together by anyone pinion 38 must have the same number of teeth inl each, and this number must be a multiple of the number of unitsA of value in the denomination to which the corresponding stud-barrel1,2, or 3 appertainse. g., twelve in the case of the pence-barrelfor the reason that as the wheel 37 receives vincrements of angular motion corresponding (in the case of the pence-barrel) to multiples of twelfths of a revolution, whereas the wheel.

11 always completes its revolution to the zeropoint, it isA necessary that the teeth of the wheels 11 and 37 should be in alinement when the wheel 11 is at the zero-point (in whatever position the wheel 37 may be left after having performed a greater or lesser number of twelfthsof a revolution) in order that the ypinion 38, which is constantly in gear with wheel 11, may slide into gear with the wheel 37 at the next operation of the machine. The wheels 11 37, pertaining to the pence-barrel, therefore have by preference twentyfour teeth, while those pertaining to the shillings and pounds barrels have in each case twenty teeth. From the foregoing it will be evident that as each pinion 38 is constantly in gear with the corresponding wheel 37 it will at each operation receive increments of angular I motion corresponding to multiples of the pitch of its teeth', so that whatever the number of teeth in the pinion 38 two adjacent teeth will always y(at the completion of an operation of registration) be in angular position to engage with the xed stud 66, whereby the shaft 31, 32, or 33 is locked in position of rest.y

The shafts 31 32 33 are respectively geared by wheels 6768 69 with wheels 70 71 72,'re-

spectivelyconnected with the pence typewheel 34, the units-wheel 35 o f the shillings 'type-wheels, and the units-wheel 97 of the pounds typewheels, so that by the 4rotation of shafts 3l 32 33 the type-wheels with which they are thus geared receive increments of angular motion at successive Aoperations of the machine. When a type-wheel of lower denomination has performed a complete revolution, the' type-wheel of the next higher denomination receives an angular movement corresponding to a' unit of that higher denomination by means of the carrying-over or transfer mechanisms. (Illustrated in Figs. 1 6, 7, 8, and 11.) There are two such transfer mechanisms, the one for advancing the unitsof-shillings type-wheel 35 `to the extentof one unit for every complete revolution of the IOO IIO

pence type-wheel 34 and the other for advancing the pounds type-wheel 97 to the extent of one unit for every complete revolution of the units-of-shillin gs type-wheel 35. These transfer mechanisms are similar in construction and operation, but the cams by which they are operated are respectively adapted to produce the different amounts of angular advance required in the case of the corresponding type-wheels and are timed to actin succession and not concurrently, so that should the next operation of registration involve transfers both from pence to shillings and from shillings to pounds the transfer from pence to shillings shall always precede that from shillings 'to pounds in order that both transfers may be eected at the one operation of the machine. Each transfer mechanisrn comprises a cam disk 73, fast on the shaft 22 and engaging by its groove 74 with a stud on the tail end of a bell-crank lever 7G, pivoted to rock upon a fixed shaft 77, each lever 76 being formed for convenience of pairs of plates riveted together,with distance-pieces between them. To each lever is pivoted at 78 a propelment-pawl whose claw 79 is normally held out of operative position by the tail end SO of the pawl being engaged by a latch 8l, from which it is only released when the said latch is tripped.

In Fig. 6 is shown the mechanism for transferring twelve-pence units from the pence type-wheel 34 as a shilling unit to the unitswheel 35 of the shillings type-wheels. Upon this wheel 35 are fixed the studs S2, (ten in n umber,) upon which the pawl 79 acts when the latch 8l is tripped by a stud S3, fixed to the pence type-wheel 3l. Normally the lever 76 is rocked idly at each revolution of its operative cam; but when (the wheel 34C having completed one revolution) the latch'Sl is tripped by the stud 83 the pawl 79 is permitted to engage one of the studs 82, and at the neXt oscillat-ion of the lever 76 the unitsof-shillings type-wheel 35 is advanced one step. The latch 8l participates in the angular motion of theLlever 76 and is guided bya pin and slot S4 and by a corresponding slot 35 atits. rear end engaging the shaft 77, so that the latch can receive motion in the direction of its length, the latch being normally pressed forward by a spring 36, xed to the lever 76, and caused to present as'houlder87 at its forward end in position for engagement with the tailend SO of the propelment-pawl. A spring S8 tends to throw the propelmentpawl 79 intooperative position, but is normally prevented from so doing by the latch l81, the shoulder S7 of which is caused to en- 6o.

gage with the tail 8O of the pawl when a rearwardly-directed arm 39 on the pawl is caused by the oscillation of the lever 76 to strike Aagainst a xed rod 90.

In Fig. 6 the pawl 79 is shown in engagement with one of the studs 82 of the units-ofshillings wheel 35, and the upper arm of the lever 76 is shown as in course of oscillation to the dotted position at the right for the purpose of advancing that wheel to the extent of one unit. At the next oscillation of the lever 7G to the dotted position at the left the arm 89 of the pawl 79 will strike the rod 90, the pawl will be retracted, and the shoulder 37 of the latch 8l will springinto engagement with the tail end of the pawl, and thenceforth the lever 76 will be rocked idly at each revolution of its cam until the latch is again tripped after the completion of another revolution of the pence type-wheel 3l. The tripping of the latch is effected by the stud S3 on the pence type-wheel striking the beveled end of a thrust-plate 91, having parallel slots 92 93, respectively, adapted to slide upon the rods and 77, the thrust-plate 91 being connected to the latch Sl by a stud 9i on the latter engaging in a slot 95 in the former, said slot being curved to an arc of a circle, so as to permit the latch 3l and its pin 9-1 to participate in the rocking motion of the lever 76. When the stud 83 (bythe revolution of the pence-wheel 3l in the direction of the arrow) strikes the beveled end of the thrust-plate 91, it forces thelatter backward and causes it to retract the latch 8l by the pin-and-slot connection 9i 95, thus allowing the propelment-pawl 79 to come into the operative position shown.

The number of keys in the shillings-bank is limited to nine, and to enable values up to nineteen shillings to be registered the key representing the value of ten shillings is (for a reason hereafter explained) placed in the bank of keys of higher denomination in which the unit ofvalue is therefore the halfsovereign, the successive values represented by successive keys in thisrlatter bank advancing by increments of ten shillings. In consequence of this arrangement the tensof shillings type wheel 9G and the units-ofpounds type-wheel97 turn together as one ,and the wheel 97 has twenty type-faces, each number from Zero to 9 being duplicated, while the tens-of-shillings type-Wheel 96 bears only ten types,each representinga single unit, these types being alternated with vacant spaces and being alined with alternate types on the units-of-pounds type-wheel 97, so that each step of angularadvance of the combined Wheels represents anl increment of value of ten shillings. In consequence of this arrangement the transfer mechanism which operates between the shillings and pounds Wheels and which is precisely similar in construction to the transfer mechanism already described is brought into operation by the' tripping of its latch 8l by a stud 83, fixed to the units-of-shillings wheel 35, and the propelment-pawl 79 takes effect upon one of a set of pins 82 on the units-of-pounds wheel 97.

As the pinions 38 are locked, as above described, at the time when the transfer mechanisms come into operation, it is necessary to provide for the independent rotation of the units-of-shillings type-Wheel 35v and of the IOO With this object these wheels are not fast with the respective sleeves by which they are connected with the gearywheels 71 v72,",but are in the form of rings, as

indicated in Fig. 11, each mounted to rotate upon a disk 100, fast o'na sleeve 101, connected to the gear-wheel 71 or 72, as the case may be, the ring having internal teeth 102, engaged by a spring-jumper 103, fixed on the disk 100,

so that when the type-wheel is to he operated by the gear from the stud-barrel the jumper 103 Will act as a driving-pawl; but when, the driving mechanism being locked, the transfer .mechanism comes into action the teeth 102 will slip over thej umper. The spring-j umper 103 also serves to insure the accurate register of the type for printing purposes.

The tens-of-pounds type-wheel 98 and the hundreds-of-pounds type-Wheel 99 have each only a single set of type from 0 to 9 and turn loose on that sleeve 101 which connects the gear-wheel 72 with the units-offpounds wheel 97, and the tens-of-pounds wheel 98 is actuated fromv the nnits-ofK-pounds wheel* 97, and the hnndreds-of-pounds Wheel 99 is actuated from the tens-of-pounds wheel 98 by suitable known transferring mechanism as, used in rnnmerators-esuch, for example, as shown in Figs. 9, V10, ll-and which, being well known, need not be described.

The tail ends ofthe key-levers 17 are pressed upon by a main weight-bar 108, carried by a pair of arms 109, pivoted on the key-lever axis 16, this bar being continuous across the three banks of keys, so as to be raised by the operation of a key in any one of the banks and so as when the operation of registration is cornpleted Ato return to normal position the key or 'keys so depressed. i In order to prevent retrograde motion of the Weight-bar 108 before it has performed its complete stroke in theone or the other direction, it is provided with a doubleactingnonretnrn pawl110, adapted to engage with a stationary rack 111 ineither direction of motion, this pawl being pivoted at 112 to the back of the weight-bar and controlled byoppositely-actingsprings 113,which allow it (when in engagement with the teeth of the rack 111) to assume either of oppositelyinclined positions, according to the direction in which the weight-,bar happens to be moving, clearances at` the ends of the rack 111 allowing this pawl to assume its mid-position at the end' of each stroke of the weight-bar 108 in readiness for the next movement of the latter. y

A hooked detent 114 is pivoted at 115 to the frame of the machine and is caused by a spring 116attached to its shorter arm 117 and to the frame,`to engage `with lthe lower edge of the weight-'bar 108 when the latter is 4raised toits highest position, so as to retain said bar in that position until a tappet 118, fast on the shaft 50, strikes the arm 117 of the detent, ywhich it does when said shaft has been revolved sufficiently to bring about the 'at 131 to the frame.

operation of the various mechanisms of the machine, which are dependent on the performanceof a revolution-by the shaft 50, whereupon the weight-bar 108 is released and allowed to fall. To insure the descent of the weight-bar 108, it has fixed toit at one end a thrust-bracket 119, with -thenpper end of which a stud 120 on the wheel 51 (which is fast on the shaft V50) bears at a given point,

in the revolution of said shaft, as shown in dotted lines in Fig. 3, so as to force the weightbar to complete its downstroke should its own weight be insufficient to overcome any accidental resistance or should the weightbar be prevented from falling by the operator keeping a key depressed. When' (after the action of the tappet 118 and before the completion of its revolution by the shaft 50) the weight-bar thus falls or is forced down by the stud 120, it is held down until Vthe shaft 50 has completed its revolution by a latch-bolt 121,- Fig. 3, engaging with a lng 122 on the end of the weight-bar, the bolt being slotted and workingon guide-studs 123 and being projected into engagement bya spring 124. It is retracted from engagement with the lug 122 when the/main shaft 50 completes an entire revolution by a cam 125, which turns with the wheel 52 and strikes a lever 126, coupledv to the latch-bolt 121.

The shaft 50 is rotated by hand in the direction of the arrow, and itis prevented from retrograde motion by wa silent or friction-operated detent 127 of bell-crank form,pivoted K The tail end of this detent is slotted, and inthe slot is engaged the end of anv arm 128 on a split or spring ring '129,'embracing, friction-tight, a grooved hub 130 on the wheel 52,so that when said wheel is turned in the one direction the detent 127 will be pnt out of action and thrown back againstfa stop 127, whereby further rotation of ring v129 Ais prevented; but immediately the wheel -52 commences to be turned backward the nose of the detent 127 will be thrown into engagement with the teeth of wheel 52 and so prevent retrograde' movement of the shafts 22 and 50. A

The main shaft 50 is prevented from being turned forward until after a key-lever in one or other of the banks has been operated by a locking-detent 132, engaging in a notch'in a disk 133, fastwith the wheel 52. This detent V132 is carried by an arm fixed on a bell-crank lever 134, pivoted at`135 to the frame, the tail end of this lever 134 being drawn down4 by a sp'ring13ta to throw the detent 132 into engagement with the notchin the disk 133 and raised to disengage the detent by a stud 136 on the main weight-bar 108 when `the latter is lifted (as shown in dotted lines in Fig. 3) by the operation of one of the'key-levers 17, the backward' movement of the detent 132 being limited b v a stop 132 on the frame.

The weight-bar 108 serves not only `to dev press the tail ends of the key-levers 17, but

also as a couplerbar to couple togetherjkeys IOO IIS

in dillerent banks (whose operation may be simultaneously initiated) in order that the continued pressure on one only of such keys shall suffice to insure the performance of a complete stroke by both or all of these keys.

The weight-bar 10S furthermore serves as a locking-harto prevent the subsequent operation of any other key after a key in one bank `(or keys in different banks) has or have simultaneously been operated and until the completion of all the operations of the machine in respect of the key or keys which may have been so operated.

The actuation of two key-levers in the same bank,whethersimultaneouslyorsuccessively, is prevented by known means-such, for example, as sliding balls or bolts confined in a tube 137, cross-slotted to give passage to the key-levers, the balls or bolts admitting only one key-lever at a time between them. The means of preventing the simultaneous actuation of more than one key in the same bankl are independent for different banks, so that the simultaneous actuation of two or more keys in. dillerent banks will be permitted. The successive depression ot' keys in different banksis, however, prevented by the weightbar 108, which, as above mentioned, acts both as a coupler for coupling the key-levers that have been simultaneously actuated and as a locking-bar for locking the remaining key-V levers against actuation. For this purpose the weight-bar 108 is curved on its inner face in the direction of its height to a radius struck from the key-lever axis 1G, and tothe tail end of each key-lever 17 is pivoted at 138 a latchlever 139, (preferably formed ot'a pair of plates riveted together and straddliug the key-lever 17,) having a nose 140, adapted to engage the upper edge of the weight-bar 108, which it is caused to do by the contact of a frictionroller 1 41 on the upper end of the latch-lever, with the inclined face 142 of a stationary cam extending across the machine and common to' the latches of all the key-levers. The engagement of the nose 140 with the weight-bar 108 takes place immediately a key-lever comlnences to be moved, and this engagement is maintainedthroughout the stroke of the keylever by the roller 141, bearing against the face 143 of the fixed cam, which face is also struck to a radius from the key-lever axis l'and is of an angular amplitude substantially equal to that of the stroke of the key. VheD, the operation ot' registration having been completed, the Weight-bar 108 is allowed to fall and so brings down the key lever or levers which may have operated, the disengagement of the latch 140 from the weightbar is .effected by the tail end 144 of the said latch striking a xed cross-bar 145 and so returning the latch to normal position, as shown in Fig. 2. The connection of the key-lever actuated with the Weight-bar 108 through the medium of the latch being thus maintained throughout the stroke of the keylever, it follows that once the latch has been connected to the weight-bar 10S the key-lever must necessarily accompany the Weight-bar throughout its stroke, so that if the latches pertaining to key-levers in different banks be coupled to the Weight-bar by simultaneously initiating the actuation of those key-levers the completion of the strokes of all those keylevers will be brought about by continuing the pressure on one of the keys only.

As the upper edge of the weight-bar 10S, with which the noses 140 of the latches engage, is only just below the level of those noses, it follows that immediately the weightbar begins to be raised by the operation of any key-lever its inner curved face will thenceforth be presented immediately over against and close to the noses 140 of the latches pertaining to the keys which have not been actuated, thus preventing such angular movement of these latch-levers as is necessary in order to permit the rising of the corresponding key-levers. The weight-bar will therefore act throughout its stroke as a stop or locking device to prevent movement of those keys which Were not actuated concurrently with the weight-bar itself, the angular extentof the innercurved face ofthe weight-bar being such thatit will thus act as alocking-bar throughout its whole stroke. By this means when a key has (or two or more keys in different banks simultaneously have) been actuated the subsequent movement ot any other key will be absolutely prevented until the completion of the record in respect of the key or keys which may have been actuated.

To each .key-lever 1.7 corresponds aV tablet 146, carried by a vertical stem 147, working in guides and resting on the key-lever, so that when the latter is actuated the tablet for indicating to the customer the value of the key will be raised into position to be exhibited at a window in the upper part of the casing of the machine; but When so raised it will still be concealed until the completion ot' the recording operations by a blind 14S, attached to a spring-roller 149 below and a second roller 150 above the level of a window 152 in the casing of the machine. The blind has an aperture 151, which by the winding of the blind on the spring-roller 140 when the Weight-bar 108 is raised) is moved out of register with the window 152 in the casing and is only moved into register with said window to exhibit the tablet or tablets which may havebeen raised when by the'fall of the weight-bar the upper part of the blind is wound on the roller 150 through the medium of a cord 153, attached to the weight-bar and to a pulley 154 on the axis of the roller 150. This blind when drawn down by the springroller may exhibit a notice 'to the effect that the transaction has not yet been registered, this notice being withdrawn and the tablet becoming visible only when the registration is completed by the printing of the record. Each tablet-stem 147 has a lug 155, which when the tablet is raised engages with a latch- IOO IIO

bar 156, whereby the`tablet or tablets raisedv pivoted at 164 to lugs on the back of theV weight-bar 108, motion about this pivot being limited in onefdirection by a heel 165, so that as the weight-bar rises the lever 160 will be forced back by the roller 162, bearing against its edge 161, and will so rock the latch-bar 156 as to release and let fall the tablet or tablets retained by it in the raised position since the previous operation of the machine. To insure the prompt fall of the tablets, a helical spring`147 may be applied to act oneach stem 147, so as to tend to force it down.

On the fall of the weight-bar 108 the roller 162 strikes against a shoulder 166 of the lever 160, and its supporting-arm 163 being free to swing in the upward direction the roller has uo action on the lever 160 during the descent of the Weight-bar, so that the tablet or 4tablets which 'have been raised at this operation will be retained in position to be exhibited.

The money-'drawer 167 is guided by rollersl 168'and is retained in the closed position ing the time-record are actuated from a clock,`

as hereafter described; They are mounted in axial alinement with the type-wheels for printing the detail and total cash-records and, like the total-cash-record type-wheels, they turn loose on an axis 177, Which may either be a dead-spindle or a prolongation of the lpence detail type-wheel spindle 13. The types 01' all the type-wheels after being brought into printing position are inked by means of an inking-pad 178, carried in a frame 179, having arms 180, by which it is pivoted at 181v to the side limbs 182 of a rocking yokeframe pivoted at 183 on fixed studs carried by the frame of the machine, so as to enable the pad 178 to be first swung into position for inking the line of types which are to be printed from and to be then pressed against those types. These two movements are produced by the action of a cam 184, fast on the main shaft 50 of the machine, ysaid cam acting (in opposition to a spring 185) against the end of Y a thrust-rod 186, longitudinally guided by slots 187,*working on `iixed studs 188,-a dog 189 at the front end of this thrust-rod engaging in a notch'190 in one of the arms 182 of the yoke-frame, so as by the forward movement of the thrust-rod 186 to cause the pad to be swung into inking position, (shown by dotted lines in Fig. 4,) in which position it comes against a stop 193. In this position the dog 189 escapes from the notch 190, but rides upon a surface on the arm 182 of the yoke-frame, so as to retain said frame in the position to which it has been brought. Meanwhile a lug 191 on'the'tail end of one of thev arms 180 of the pad-carrying frame has been brought (in consequence of the angular motion of the yoke-frame about the axis 183) into the path of asecond dog 192, forwardly projecting from the end of the thrust-rod 186,

`so that by the further movement of said vthrust-rod produced by the cam 184 the padcarrying frame 179 will be swung on its axis 181, so as to cause the pad 178 to be pressed against and to ink the line of type. When the thrust-rod 186 then escapes from the cam 184, it is retracted byits spring 185, and the pad-carrying frame is swung back on its axis by springs 194 to an extent limitedby studs 195 on said frame coming againstvshoulders on the arms of the yoke-f rame 182, after which the dog'189 becomes rengaged in the notch 190 and the yoke and pad-carrying frames are swung back about the axis 183 to their original position.

In order to insure uniform inking and an elastic pressure of the pad 178 against the line of type,-the pad 178 is held loose in its frame and is pressed against a marginal seat therein o by a backing-plate 196 and springs 197.

The impressions of the inked types aremade upon a continuous strip of paper 198, drawn from aspool 199 and Wound on another spool 200 by a step-by-step motion derived (through a ratchet-and-pawl feed mechanism 201 202) from the movement of the vibrating platencarrying frame 203, in which the spools are mounted, the said frame carryinga rubberfaced platen 204, over which the paper strip is drawn and by which the paper is pressed against the inked line of type. The journals ofthe let-off and take-up spools 199200 turn in bearings in slots 205 in the cheeks 203 of the platen-carrying frame, so as to admit of the easy insertion and removal of the spools, the journals of the take-up spool 200 being retained in their bearings byjumper-springs 206 and the strip of paper 198 being led from the spool 199 to the spool 200, around guiderollers and over the platen, as shown. The side cheeks 203 of the platen-carrying frame are braced together by suitable cross-rods, which may also form the axes for the guiderollers, and the said rframeis pivoted to swing on journals 207, received in slotted bearings in the frame of the machine,\so as to permit of the easy removal of the entire platen-carrying frame `for the purpose of changing the spools or inspecting the series of records.

' The ratchet-wheel 201 is fast on the axis of ICG IIO

the take-up spool 200 and is engaged by a f spring-detent 208 in order to maintain the tension of the paper and is also engaged bythe feed-pawl 202, which is pivoted at 209 to the frame of the machine and is pressed into engagement with the ratchet-wheel 201 by a spring. By the vibrating motion of the platencarrying frame in the direction of the arrow the paper is pressed against the inked type to produce the impression, and the pawl 202 is caused to ride over and to engage with the nexttooth of the ratchet-wheel, so that on the return movement of the platen-frame the pa perstrip will be taken up tothe extent ofone tooth of the ratchet-wheel.

The side cheeks 203 ot' the platen-frame are pivotally coupled to a pair of gudgeons 210, carried by a yoke 211, attached to the front end of a rod 212, whose other end is provided with a slot 213, whereby it is longitudinally guided upon the shaft 50. In order to permit of ready connection and disconnection, the parts 203 211 are coupled by the cylindrical gudgeons 210, having formed on them dats which when the parts are in a certain angular relation to one another can enter slots leading to the circular bearings in the cheeks 203, so that when the parts 203 211 are in working relative position secure connection will be insured. Vibratory motion is im parted to the platen-frame, the motion in the "direction of the arrow shown alongside rod 210 being performed in two stages at different speeds, the first stage by a cam 214, fast on the main shaft 50, acting upon a stud and roller 215, carried by the pull and push rod 212, and the second stage by the sudden action of another cam 216, also mounted on the shaft 50,' but loose thereon, the latter cam being carried by a spring-barrel 217, loose on shaft 50, whose spring 217L is attached at its outer end to the. periphery of the barrel 217, as shown in Fig. 5a, and at its inner end to the shaft 50, 'so as to be wound up by the revolution of` said shaft, while the barrel is pre- Ventedl from turning until a given moment, whereupon its cam 216 is permitted to act suddenly under the impulse of the spring. The

barrel 217 is held and released by a sort of cylinder escapement (shown in Fig. 5) formed of a tooth 218 on the barrel engaging with anV escapementcy1inder 219, carried by a geanwheel 220, pivoted on a fixed stud on the framing'of the machine and in gear with an equal wheel 221, fast on the main shaft 50. \Vhile the spring of the barrel 217 is being wound the tooth 218 abuts against the outside of the escapement-eylinder 219, which is meanwhile revolved so that at a given point in its lrevolution the gap in the cylinder 219 first comes opposite to and receives the tooth 218 and thereafter permits the tooth 21S to escape, whereupon the barrel 217 and cam 216 are allowed yto perform a sudden revolution under the impulse of the spring, whose action has thus been delayed until the proper moment. The slow action produced by the cam 214, acting on stud-roller 215 of rod 212, Vibrates the platen through the greater part of its stroke and brings the paper nearly, but not quite, into contact with the type, as

218 of the spring-barrel 217 escapes from the escapement-cylinder 210) is caused to perform a sudden revolution, in the course of which it acts on the stud-roller 222 of rod 212, as shown in Fig. 4b. By this sudden revolution of the cam 216 the stroke of the platen is completed by an almost instantaneous movement, whereby the impression is produced without the possibility of such prolonged frictional contact of the paper with the type as would interfere with the going ot' the clock by which the time-record typewheels are set. The platen is retained in the intermediate position (until the spring-barrel cam 216 is allowed to come into operation) by the circular portion of the cam 214 acting on the stud-roller 215, as shown in Fig. 4, and the return motion of the platen is produced in one stage (after the cam 216 has returned to normal position) by the action of the cam 214 on another roller 223. 224 is a slot in the casing of the machine, through which a loose slip ot' paper may be introduced, together with a slip of carbon-paper, in order to take the impression thereon as well as on the continuous strip of paper 198. In order to enable this separate imprint of the aggregate-record type-wheels and of the time-record type-wheels to be obtained without any key corresponding to the stud-barrels 1 2 3 being operated, a special key 225, Figs. 1 and 3, is provided, this key forming a continuation of the locking-lever 134, so as by depressing that key to enable the locking-detent 132 to be disengaged in order to permit the main shaft 50 and the shaft 22 to be rotated. The rotation of the shaft 50 operates the inkingpad and platen-frame, as above described.

Vhere, as is sometimes the case, several inspectors are employed, whose duty it is to supervise the use of these cash-registering machines by the employees at several branch establishments, it is desirable that the inspector (by whom the imprint of the record is taken upon a separate strip of paper introduced at the slot 224, as above mentioned) should be himself identified. For this purpose each inspector would be provided with a portable plug-key 226 to be inserted through a keyhole in the casing and frame of the machine in such position as to present a special type 227 on its inner end to the inking-pad in order that au imprint may be taken from said type alongside ofthe time-record. In order to insure the complete insertion of this plug-key 226, it is provided with a web or tin 22S, havinginclined surfaces at its end, so as when the key is first inserted to cause a sliding bolt 220 to be forced backward, so as to cause its nose 230 to be forced into a notch 231 in a disk 232, fast on the shaft 22, thus preventing the rotation of that shaft and also ICO IIO

ISO

'oi' the main shaft 50until the keyl is fully inserted, whereupon the bolt 229 is forced forlWard again by a spring 233, thus Withdrawing the nose 230 from the notch 231 and permitting the rotation of the shafts.

In'order to lock the cash-'registering keys out of business hours,v a latch 234 is adapted .toengage with a lug 235 on the thrust-bracket 119, attached to the Weight-bar 108, as above mentioned, so that the weight-bar, and therefore the cash-registering keys, cannot be operated. ,lf it'be desired to also lock the time-` vkey 225, this latch 234 may also be adapted erative position, this tail end 237 being enf gaged by pin and slot or otherwisewth the slide-plate 239 of a lever-lock provided With the usual combination of tu mbler-levers and. adapted to be operated by a key 240 for the purpose of unlocking and relocking the cashregister atvthe commencement and close of business.

The setting in position of the time-record type-wheels 174, 175, and 176 so as to print4 a record of the time on each occasion that the main shaft 50 is rotated (for the purpose either of recording a cash transaction or of making a time-record only) is permitted. by the operation of la cam 241, fast on the main shaft 50, acting on a lever-frame fulcru med at 242 `and formed ofa bridge-piece 243, on which the cam 241 acts, and a pair of arms 244, carrying at their free end a cross-bar 245, adapted to bear upon three levers 246247 248, fulcrumed on a spindle 249 and each raised by a separate spring 250, these levers 246 247 248 terminating in segmental racks 251 252v 253, respectively in gear with pinions 254 255 256, respectively corresponding to and turning as one With the units-of-minutes typewheel174, the tens-of-minutes type-wheel175, and the hours type-wheel176, the pinion 255 being connected to the type-Wheel 17 5 through the medium of a sleeve upon which the pinion 256 and type-Wheel 176 turn. The down- Ward movement of the rack-carrying levers 246, 247, and 248 is determined by the cam 241, whereby the type-Wheels are brought to and maintained at their normal vor inoperative position, as indicated in Fig. 12, until by the revolution ofthe main shaft 50 and cam 241the springs 250 are permitted to act for the purpose of simultaneously setting the three type-Wheels 174, 175, and 176. For this purpose the amplitudes of the strokes of the respective segmental -rackcarrying levers 246, 247, and 248 are determined by pallets 257, carried by the tail ends of those levers respectively coming into contact with timecams 2,58 259 260, mounted side by side upon the hour-arbor 261 of a clock, the units-ofminutes cam 258-and the tens-of-minutes cam 259 turning together as one and being eta-gasa connectedto the arbor 261 throughy the medium of a disk 262, fast on the arbor 261, the driving connection between said disk` and the units-of-minntes cam 258 being through the medium of a spring 263, attached to a stud 264 on the disk 262 and to a stud 265 on the cam 258. The stud-265 passes throughaslot ,266 in the disk 262'and is normally held against the forwardend of said slot by the spring 263,

the purpose of this spring connection being `to enable the rotation of the arbor 261 and vdisk 262 to contin ue, and thus avoid stoppage of the clock, When, as hereafterexplained,

:the rotation ofV thecams 258 259 is tempolrarily checked, as hereafter described, the

forward end ofthe slot 266 acting as a stop todetermine the-normal angularposition of the cams 258 259 relatively to the disk 262.

The units-of-minutes cam 258 has six arms,

each formed with ten steps situated at progressively and equally diminishing radii.

VThe six arms of this cam correspond, respectively, to intervals of ten minutes, and each lof the ten steps of each arm therefore corresponds to anl interval of one minute. The ten's-of-ininutes cam 259 is an ordinary snailcam whose periphery isdivided into six steps situated at progressively and equally diminishing radii', each of the six steps of the cam 259 vcorresponding to the ten steps of one of the arms of the units-of-minutes cam 258, so

that each step of the caml 259 corresponds to the movement of the cam during aninterval of ten minutes. Theoretically the lengths of the steps of cams 258 259 are determined by the combined angular movements of those cams and of the respectively corresponding levers 246, 247,7and the beginning of each step of cam259 should coincide in angular posi- Ation with the beginning of the corresponding arm of cam 258, (assuming the pallets 257 to have no thickness and to be carried by leverarms of equal length.) In order,. however, to compensate for the necessary thickness of the pallets, and so render the angular amplitudes of the minute steps of cam 258 equal inter se in effect, it is necessary to diminish the angular amplitude of thestep .of greatest radius of each arm ocam` 258, so as to diminish the length of the step to an extent equal to not less than the thickness of the pallet 257, and to correspondingly increase the lengths' of the steps of least radius simi- IIO la'rly as regards the'steps of greatest and-least radius, respectively, of cam 259; but in this casethe variation of length of those-'steps is ydetermined by the fact that Whereas while the beginning of the step of maximum radius of cam 259 must coincide in angularposition with the beginning of the step of maximum radius ot' one of the arms of cam 258 the cam extent of one-twelfth of a revolution at the completion of every hour through'the agency of a ratehet-wheel 267, fast with the hourscam 260 and engaged by a driving-pawl 268, pivoted at 269 to a lever 270, the pawl being pressed into engagement with the ratchetwheel by a spring 271. The lever 270 is in one with a lever 272, the two levers being pivoted at 273 to the clock-frame, and the lever 272 terminating in a stud 274, which is acted upon by a snail-cam 275. This cam 275 is fast on the hour-arbor 261 and has but a single step whose angular position is such that during every hour the levers 270 272 are lifted and the driving-pawl 268 is retracted until it comes into engagement with another tooth of the ratchet-wheel 267, and on the completion of the hour the edge of the step passes under and clear of the stud l274, and so permits the levers 270 272 to fall suddenly and move the pawl 268 forward under the impulse of a spring 276, attached to the combined levers 270 272 and to a fixed point, so as to cause the instantaneous advance of the hours-cam 260 to the extent of one tooth of the ratchet-wheel 267-. During the retraction of the driving-pawl 268 the hours-cam 260 is held stationary by a jumper-spring 277, en-

gaging with a circle of twelve stop-pins 278,

fixed to the ratchet-wheel 267, excessive motion of said Wheel during the driving stroke of t-he pawl being prevented by a check-detent 279, carried by the lever 270, coming into the path of one of the stop-pins 278 at the termination of the driving stroke of the pawl 268.

In order to accurately cordinate the movement of the combined minutes-cams 258 259 with that of the hours-cam 260 at the instant when the change from one hour to the next is made and also in order to cause every change of position of cam 258 (at which a step of maximum radius of that cam is presented to the pallet 257) to be made suddenly, a detent 280 is presented in the path of each of the limbs successively 'of the cam 258 just before each such changey of position, so as to temporarily cheek the rotation o f the combined cams 258 259, this detent 280 being disengaged, as hereafter described, so as to permit the combined cams to be moved forward suddenly by the action of the spring 263. rThe disengagement ofthe detent 280 is effected by one of a series of studs 282 on the disk 262 acting upon an antifrietion-roller283, bearing against the ledge of the disk and mounted on an arm 284,

which carries the detent 280 and which is pivoted to the clock-frame at 285 and is normally pressed by a spring 286'into position for engagement. At the change of the hour the disengagement of the detent 280 from the arm of cam 258 is coincident with the driving stroke of the pawl 268, so as to cause the sudden movement of all three cams 258, 259, and 269 to take place at the same instant. The

effect of the delay in the rotation of the com- Y bined cams 258 259 is to causeapossible error in time of a minute if a record be printed during any one of these short delays; butif a record be printed during the delay which occurs just before the completion of an hour this delay has the advantage of preventing a possible error of fifty-nine minutes, which would otherwise be caused if the sudden change of the hour-cam were to occur before the relatively slow change of the minutescams could take effect and if a record happened to be printed in the interim.

In order to prevent stoppage of the clock by the advancing back edges of the cams 258, 259, and 260 coming against the pallets 257 in the event of the rack-levers being brought and left in operative position, the pallets 257 project laterally each from a stud 287, mounted to turn about its own longitudinal axisin the end of the rack-carrying lever 246, 247, or

248, so that should the pallet be fouled by the radial back edge the palletwill yield andswipg aside out of the way, being normally heldin operative position against a stop by the torsion of a spring 288.

The hour-arbor 261 is driven by an ordinary spring-barrel 289 under they control of a suitable clock train and escapement 290. The barrel-spring is automatically rewound each time the apparatus is used by an eccentric cam 291, fast on the main shaft 50, acting upon a lever 292, fulcrumed upon the barrel-arbor 293, and held up to the cam by a spring 294. To this lever 292 a pawl 295 is jointed at 296 and is pressed by a spring into engagement with a ratchet-wheel 297, fast on the arbor 293, to which the inner end of the barrelspring is attached, so that at each revolution of the main shaft 50 the lever 292 will be oscillated and the spring will be rewound to a corresponding extent, the extent of rewinding being so much in excess of the average extent to which the barrel runs down in the intervals between successive operations of the machine as to compensate for the prolonged period of inaction of the machine out of business hours, and so keep the clock always going. To enable this to be done, it is necessary to make provision against overwinding, and for this purpose a deflecting-cam 298 is provided, which when the barrel is fully wound is brought into the path of a stud 299 on the pawl 295, so that during the driving stroke of the pawl the stud 299 will ride up on the cam, and thus cause the pawl to be lifted out of engagement with the teeth ofthe ratchet-wheel 297. The cam 298 is pivoted at 300 and is provided with an arm 301,pressed upon by a spring 302, whereby the cam constantly tends to assume the operative post tion shown in Fig. 13. Normally, however,

that the stud 299 willpass freely beneath it,

v the'cam being moved to. and retained in this als inoperative position against the pressure'of the spring 302 by an inclined cam 303 taking 1 under the ar'm 301, said cam 303 being formedv on the end of a lever 304, pivoted'at305`and having its other end engaged in a grooved collar 306, capable of turning and sliding upon a spindle 307, the cam 303 being normally held in operative position by a spring 308 acting to press the collar 306 along the spindle 307. This collar 306 i s in one with a star-Wheel 309, which is intermittently rotated under the control of a jumper-spring 310 bythe successive engagement with its armsl of a'stud 311 on the ratchet-Wheel 297. A precisely similar star-Wheel 312 is mounted to turn Yloose but not to slide upon the same spindle 307, and is intermittently rotated under the'control of a'jumper-spring 313 by a stud 314 on the barrel 289.

315 316,Which when the spring of barrel 289 is fully wound ride up the o'ne upon the other, and `so cause the star-wheel 309 to be forced away from the star-wheel `312, thereby moving the collar 306 lengthwise of the spindle 3O7-against the pressure ofthe spring 308,

and so retracting the cam 303 fromthe tail end 301 of the paWl-releasing cam 298,whichV soon,however, as by the rotationof the ratchetwheel 297 its stud 311 rotates the star-wheel 309 Vsufficiently to cause the cam-stud 315 to overtake and come into angular alinement with the cam-stud, 31,6 the pawl-disengaging cam298 will again be brought into operative position, as before described. It will thus be seen that this mechanism constitutes what may be termed a "hunting-gear, wherein the one part is continually moving away from and repeatedly being overt-aken by the other part, with the result above described. The operative position of the cam 298 is determined by a stop 317,V and the meeting faces of the stud 299 and cam 29 are so beveled and Vmeet so early in the driving stroke of the pawl 295 as to cause thelatter to be disengaged from the ratchet-wheel before it can move said wheel to the extent of a tooth, and consequently before the retaining-detent 318 can engage with a fresh tooth of the'ratchet-wheel. 4 By the use of star-Wheels and j u mper-sprlings,

as described, the action of the @ami-studs 315 316, and consequently the movement of the cam 298 into and out of operativeposition, is

The ytwo star-wheels have' upon theirradjacent faces inclined cam-studs effected suddenly, and the inclined faces of cam 298 and stud 299 are knife-edged', so thatV there is no liability of these two parts butting so as to cause breakage of the parts.

The clock and time cam.mechanisms, as

shown in Figs. 12, 13, are mounted together in a frame removable as a whole from the machinefor the purpose of cleaning orrepair, theframe being provided with flanges 319, which slide into guides 320 on the main frame vof the machine, and the clock-winding lever 292 being for thev sake of convenience kneejointed at 321 to admit of being folded down to pass beneath a cross-bar 242 of the main.

frame of themachine.

The operation of the machine for the purpose of recording a cash receipt is as follows: Supposing the amount to be recorded to be onershilling, the key so marked is depressed, and the tailend ofthat key-lever 17 raises the detent 26 of the same key-lever into lthe path of the corresponding stud 25 on the barrel 2 at the same time thatV it also raises the keylever` motion-transmitting cross-bar frame 18 19 and simultaneouslythe weight-bar 108 109. In thisposition the key-lever 17 is retained by the engagement of its ,latch 140 with the weight-bar 108 and by the engagement of said Weight-bar with its detent 114 until the said detent is released by the operation hereafter described.'v By the raising of the cross- .bar frame 18 19 the stop 41 is disengaged, and the coupling-pinion 38 is by its spring 40 disengaged from its'locking-st'ud 66 and thrown into gear with the intermediate wheel-11,A

spring 5 of the barrel 2 to be slid out of en-A gagement with the abutment-arm 64 and into engagement with the other member 57 58 of the clutchv in readiness for effecting there- Winding of the barrel. Further, by the same movement of the cross-bar frame 18 19 the cam 2O causes the detent 23 of the lever 21 to be Withdrawn from the'stud 24 of the barrel 2, whereupon said barrel revolves to the extent permitted bythe key-lever detent 26and the corresponding stud 25. By the partial rotation of `the barrel 2 thus permitted the shafts 14 32 each perform a partial revolution,

whereby the yshilling type-wheels 8 and 35 are revolved to an extent corresponding tov the partial revolution of the barrel 2 the effect being to bring into printing position the numeral onv the aggregate type-wheel 35 next following the-one which had previouslyv occupied the same position.

The depression ICO - the numeral 1 in the detail type-Wheel 8 and tion by the latch-bar 156,- while the rising of the weight-bar 108 permits. the `blind148 to be drawn down by its spring-roller 149, so as to conceal the tablet raised. By the rising of the weight-bar'108 its stud 1236 carries up the lever 134, thereby disengaging the detent 132 from disk 133, so as to permit shafts 22 and 50 tok be revolved. As these various movements above described follow instantaneously onv the depression of the key, the shaft 50 may now be given one revolution, whereby the following mechanisms are operated: The shaft 22 receives one revolution, whereby. the barrel-rewinding clutch, which was thrown into gear, transmits motion to and rewinds the springof barrel 2. The cam 47 on shaft 22 moves the slide-rod 39 to the left in Fig. 1, thus disengaging the pinion 38 from the intermediate wheel 11 and holding it in rengagement with its locking-stud 66. The cams 73 on shaft 22 impart rocking motion to the levers76 of the transfer mechanism. By the completion of the revolution of shaft 22 the disk 60 is returned to normal angular position, wherein (in consequence of the withdrawal of the roller 61, as hereafter described under the operation of shaft 50) it is caused by its spring 63 to become rengaged with the abutment-arm 64. By the revolution of shaft 50 the pallets of the segmental-rack-carrying levers 246 247 248 of the time-record typewheels are permitted by the cam 241 on shaft 50 to make .contact with the respective timecams 258 259 260, soas to bring the time typewheels into position to print the time-record, as determind by the angular position of the time-cams. The cam 184 on shaft 50 first swings the inking-pad 178 into position opposite the type to be inked, then presses it against those type, and then permits it to be returned to normal position. Then the cam 214 on shaft 50,. acting on the stud-roller 215 of rod 212, swings the vibrating platenframe slowly forward until the paper on the platen is close up to .but not touching ,the inked type. [Meanwhile the revolution of shaft 50 has been winding up the spring'of barrel 217 and rotating the escapement 219, which before the cam 214 ceases to act on the stud-roller 215 permits the tooth 218 of the barrel 217 to escape, thereby allowing said barrel and the :cam 216 to suddenly revolve, by which movement the said cam causes the platen` and the paper stretched thereon to strike suddenly against the inked type and to instantly recoil therefrom by reason of the elasticity of the platen. The cash and time records having thus been printed, the detent 114, by which the weight-bar 108 is until then held up, is disengaged by the tappet'118 on the shaft 50 and the weight-bar is allowed to fall. The descent of the weight-bar returns the key which has been operated to normal position. The return of the key-lever 17 causes (a) the rengagement of the stop 41, whereby the coupling-pinion 38 is retained in` the locked position, to which it has already ybeen returned by the cam 47; (Zi) the rewinding-clutch-operating roller-61 to be withdrawn; (c) the cam 20 to bring the detent 23 into the path of the stud 24; (d) the key-lever detent 26 to be disengaged from the stud 25 on the barrel 2, whereupon the barrel is permitted to be revolved by its spring through the complement of its revolution until ai;- rested in normal position by the stud 24 meeting the d'etent 23. By this complementary rotation a corresponding amount of movement is imparted by gears 10 11 12 to the shaft 15 of detail type-wheel 8, which, like the/barrel 2, is thus returned to zero position; (e) lastly, by the return of the key-levver 17 its latch 140 is caused (bythe nail end of thev latch-lever` 139 striking the rod 145) to be disengaged from the weight-bar. The revolution of the shaft 50 also causes the cashdrawer 167 to be unlatched. By the descent of the weight-bar 108 the blind 148 is drawn, so as to uncover the tablet 146, which has been raised. 1f the weight-bar does not fall freely, it is forced down by the stud 120, rcvolving with the shaft 50. When the weightbar reaches its lowest position, it is engaged by the latch-bolt 121 and is thereby retained until the completion ofthe revolution of shaft 50, whereupon the latch-bolt is retracted by the cam 125 at the same moment that the detent 132 is caused by the spring 134L to enga-ge with the notchin the disk 133,-and so tolock the shafts 22 and 50 against further revolution until the next actuation of a key. On the completion of the revolution of the shaft 50 the segmental-rack-carrying levers 246 247 248 of the time-record-printing wheels are moved out of contact with the time-cams 258 259 260 by the cam 241 and levers 244, thereby returning the time-record type-wheels to Zero. During the revolution of shaft 50 also the cam 291,carried thereby,acts on-the clockwinding pawl-lever 292 and causes the spring of the clock-barrel to be wound to an extent corresponding to the stroke of said lever unless (or until) the spring is fully wound, in which event bythe action of the hunting-gear the action of the winding-pawl 295 is rendered inoperative. l

The operation of the above-described mechanism is similar for each of the banks of keys and their associated stud-barrels and mechanisms, and if two or more keys severally situated in two or more banks be simultaneously actuated their latches 140 will be simultaneously engaged with the weight-bar 108, and they will move together as one therewith, and their several associated barrels and mechanisms will be simultaneously operated, each as above described. Vhether one key or two or more keys in different banks simultaneously be thus operated, all other keys will be locked (until the weight-bar 108 has again fallen) in consequence ofthe obstruction presented by the weight-bar 10S to any movement of the latch-lever 139 under the action of the cam 143.

d If the angular position` in which the totalizing type-wheels have been last left is-'suehv that the addition of the amount represented by the key actuated tothe amount already recorded by"thetotalizingtype-wheels will n involve the tran'sferof acomplete revolution of a wheel of lowerdenominationfas a 'unit-ofy of the studs S2 on .the wheel of higher denomination by the tripping of its latch bythe stud 83 o nthe wheel of lower denomination,

so that when the transfer-lever 7 6 is rocked by the revolution of the cam-diski' with the shaft 22 the propelment-pawl 79 will take effect on a stud 82 of the wheel of higher denomination and cause` that wheel to be advanced to the extent of one unit. Should the addition of the amount to be added tov the previonsre'cord involve the operation of both mechanisms for transferring from one denomination tol another, (as, for instance, the addition of a penny to nineteen shillings and eleven p'ence,) the propelmen't-pawls 0f both transfer mechanisms will have been brought,

. as above described, into `operative position,

but they will becaused to actin succession during the same revolution of the shaft 22 by.
